Download Path


Click the appropriate link below to begin downloading Path. Please see the FAQ page for help in selecting which file format to download.

Last updated: 9 September 2010, v1.0.11 (changelog) Click here for older versions.

Once the download is complete, please unpack the contents of the downloaded archive file and follow the instructions below.

  1. Download the latest version of the Java Runtime Environment at www.java.com, and make sure the JRE_HOME environment variable is set to its location before running Path.
  2. Install the UNPHASED software that comes bundled with Path. To do this, extract the files within the unphased-3.0.13 archive. Three directories will be created: bin/ containing executable files (unphased.sol is a Solaris 10 binary, unphased.lnx a Linux binary, and unphased.exe a Windows binary), doc/ containing documentation files, and src/ containing the source code. Make sure to include the location of the UNPHASED executable file in your PATH environment variable. Path currently supports version 3.0.13 of UNPHASED. On some systems, the precompiled binaries of UNPHASED may not work and it may be necessary to build the UNPHASED program from source with a make utility.
  3. It’s a good idea to install the latest version of your default internet browser, as well.

Once you have completed the installation of Path, we encourage you to try out the tutorial.



If your database somehow becomes corrupt (i.e. the Java Derby database is throwing multiple exceptions in the command window), and you’d like to replace it with an empty, clean one, feel free to replace your Path/database folder with the one located here (~3MB). Please note that simply clicking the “Clean Database” button in the Setup application will also empty your database, if it’s not corrupted.
